EXTENSION-RAILS.

' Specification of Letters Patent. Patented A151241, V11916. i

Application filed January 29, 1916, Serial No.'75`,004.

Tofualliwhom it may concern Be-'it known, that I, EDWIN E. SLICK, a.

vcitizeno the AUnited States, residing in the boroughof l/Vestmont, in the county of Camibria and'A State of Pennsylvania, l(whose post-office address; isV Johnstown, Pennsylvania,) have invented ,certain new, andA co'r'rimodaten carsland otherV apparatus on these'j tracks 'andA keep them close Y' to their work.`

The" illustration amidgescripaon heres withI have'shown a track composed of a pair ofusual'T-railsiand overl the` endseo these); set my extension ra1ls,wh1chare'of inverted U orchannel sectlon, which exten* sion yrails vmay vbe Y'projected forward in line withther trauckrails so as to prolongthe track as-requiredgand kept it close-to the of the standard'ftrack` rails which i's'used; whereupon the-standard track rails are in-r troduced inplace ofthe extension, rails and ythefeztension'f set' upon theV new pair of 'traek rails. This processcanbe Vrepeated indefinitely. y i

jOne of the advantagesfof my invention is dueftofthefact that itis impractical andy Yunecol'i'oin'ical' tocut track rails in'short pieces for the'purpose of extensions, be'- sides" which4 a trackso made cannot ,be kept in-closefcontact with the working face and can only come as close as the fixed lengths vof-.th'e track rails-will permit; whereas by means 4of'm'y invention the track can be kept in close" proximity to the changing vlocatio of the "working face-"at all times.

M'yinvention is particularly applicable in mcor'i'nectior'i with coal-digging machines and coal cars,which, in'order to be operated successfullyland economically, must be near the working face of the Vcoalseam; and it is also equally applicable to steam shovels, V quarryfcars', channeling machines, ditch eX- workingface, until such'time as they amount 'offextension'is equal to the length of one` tors, epuarrying machines; orfor use-,in ore mines, clay mines, salt mines, .dump tracks for forming embankments, or for wasting earth, rock `or other materials, and in fact anyplace where Va car Orother apparatus has to progress gradually into a'cut or entry; n

For the-purpose of simplicity of description and illustration, I have shown my eX- tension rail in Vconnection with a coal mine, vbut I wish it understood that it lis equally applicable to any other construction to whichfit is adapted. Referring now to drawings forming part of this specifica'- tion Figure -1 is Va side elevation of the end of a track in a rcoal mine entry or room,

the annexed sheet of showing my extension rail in position and v a mine car thereon close to thewvorlring face of the coal or other material; Figr 2 is a. top view of that portion ofthe track illustrated in Fignl; Fig. 8' is v`a transverse sectionalV elevation on an enlarged scale taken'on the line III-III of Fig. 1, and

Fig;V 4 isla' transverse sectional elevation through =my extension' rail,` also on angen-V larged scale, taken on the line1IV-IV o Figiril". ,Y Y Y Referring now to the various characters offrefcrence on the` drawings 1 represents a mine entry or room yinl general,l 2 is.l

the'working face of coal, rock or other material which'ris in process of'cutting oreXcavatlon, 3 1s a mme car located on kmy eXtension rails close to the'workingface, so that the material can be readily loaded therein. My extension rail is also adaptedto the use of coal cutting'machines, or lother apparatus, which must, ,of necessitygbelocated close to the workingface'to'undercut or shear this' Y or to otherwise'handle the material inany way.- t v j c. w

lare the ordinary track rails, shown in this-'case as' T-rai'ls, the tracks beingv mounted on metallic ties 5, provided with buttonsf, these ties and their fastenings being the subiect of mv prior patent for metallic tie, No. 1,125,888, dated January 19,1915, My yextension rails are indicated as 7, these being of inverted U or channel 'section', provided with a top portion8, forming thetreadthereoiside portions 9, and comparatively small laterally projecting base flanges 10` whereby the rails are adapted to be secured to the ties or gage rods by but-V edV tons, clips, spikes-'for other-'suitable"fmeanssfllo In order to permit the cary or other apparatus mounted on wheels to eacily pass from the track rail 4L to my extension rail 7, I prefer to bevel the top and upper portion of the sides of the extension rail as indicated at 11, although if the extension rails'are made thin, as they may be for light work,

this beveling will be unnecessary.

If we assume that the workingl face, instead of beingk as illustrated in Fig. l, is closer to the ends of the track rails 4, the extension rails are then placed on top of the track rails with. their forward ends very slightly projecting from the track rails. As, however, the excavation or cut progresses, the car or other apparatus may be run backward on the track rails 4 and the extension Vrails pushed forward up to the working Although I have illustrated my extension.

rails and other. rails as mounted upon metallic ties, they may, of course, be mounted upon the usual wooden ties, secured by spikes, or may be mounted on any other form of metal tie or with other fastenings than those illustrated. It should alsobe noted that my extension rail is of such depth that as the extension rail fits over the trackrail it just about clears V.the spikes or fastening buttons 6, there being a slight space, as illustrated in Fig. 3, between the lower surfaces of the anges lO Vand the upper parts of the buttons 6, so that the upper part of my extension rail ts closely on the topv of the head of the track rail, thereby making a very trifling distance between the threads only equal to theslight thickness of the upper part of the extension rail. By beveling the ends of the Vextension rails as illustrated, the distance between the treads where the wheels pass from the track rail to the extension rail, or vice versa, is reduced to nothing; so that the movement of cars or other apparatus over the junction is easily accomplished, this rise being no greater than other usual irregularities in such tracks.

After the extension rails havebeen projected forward until only small portions of their rear endsy rest upon the front or forward ends of the track rails, another section of track rails of standard length may be put inftheir place, and the extension rails used in connection with this new pair of rails. Rails used in mines and elsewhere are generally of standard lengths, some 30' feet, :20 feet and 15 feet in length, and my extensionrails can accordingly be made in any of .the standard lengths of track rails, so as to temporarily take the place of any of these, thus avoiding the necessity of supplying special lengths of track Vrails or of cutting and thereby spoiling the standard lengths on hand.

Although I have shown and describedrny improvements in considerable detail, I do not wish to be limited to the exact and spe- Y cilic details shown Vand described,but may use such substitutions, modifications lor equivalents thereof as are nembracedwithin the scope of my invention, or as pointedVV out in the claims.

Having thus described my invention, what Y' I claim and desire to secure Y by Letters Pat-y ent is l. Thecombination with a track rail of Y an extension .rail adapted to fit throughout its length over the tread portion thereof and f to be vmoved parallel thereof as desired.
